Application filed September of the city of Chicago, in the county ofCook andState of Illinois, have invented certain new and usefulImprovements in a Brush- Feeding Device; and I do hereby declare thatthe following is a full, clear, and exact description of the same,'reference being had.

to the accompanying drawings, and to the numerals .of reference markedthereon, which form a part of this specification.

This invention relates more particularly to an improved type ofcombination brush having an interior feed mechanism in the brush handleadapted to supply the brush bristles or hair with a paste from areplaceable filler tube forming apart of the brush handle.

It is an object of this invention to provide a brush, the handle ofwhich includes a paste carrying refiller tube. i

It is also an object of the invention to provide a material feedmechanism in the handle of a shaving brush or tooth brush, said feedmechanism being adapted for use in connection with a replaceable fillertube contain-.

1; ing a paste or other material to be fed to the brush bristles orhairs.

It is a further object of the invention to provide a brush wherein amaterial carrying tube'is adapted to be readily connected for use with ahandle feed mechanism which is ada ted to be manually operated to causematerial from the tube to be delivered between the brush bristles in.predetermined quantities.

It is an important object of this invention to provide a brush of simpleand improved construction wherein a material carrying replaceable fillertube is adapted to form part 'of the handlc'and is associated with aplugging and feeding mechanism which when manually operated is firstadapted to open up the feed outlet apertures and then feed material fromthe tube to the brush bristles.

Other and further important objects of this invention will be ap arentfrom the disclosures in the specification and accompanying drawings.

This invention (in a preferred form) is illustrated in the drawings andhereinafter more fully described. On the drawings: Figure 1 is alongitudinal section of a shaving brush embracing the principles of thisinvention, showing 24, 1928. Serial no. 664,350.

. parts in elevation and the operation in dotted lines.

Figure 2 is a transverse section taken on line 2-2 of Figure 1.

As shown on the drawings: Referring to Figures 1 and 2, the referencenumeral 1 indicates a head or shank made of hard rubber or othersuitable material and having one end reduced in diameter and externallythreaded as at'2. The head 1 is provided with a tapering recess 3 whichcommunicates with an outlet passage i ldcated centrally in the end ofsaid head 1. The head 1 is recessed at 5 and has secured therein aplurality of rubber set brush hairs or bristles 6.

Projecting through the outlet passage 4 to close the same is one end ofa plunger rod or feed rod 7 which normally closes the opening 4. Theplunger'7 is formed on one end of an enlarged feed screw 8 havingshoulders 9 and 10 respectively at the ends thereof. Formed on the otherend of the screw 8 is a stem 11 which projects through a top piece orcap 12 made of hard rubber or other suitable material. The stem 11 has aknurled button or knob 13 secured on the outer end thereof for actuatingthe screw 8 and the plunger 7. The cap 12 is formed with an externallythreaded portion 14. of reduced diameter and is recessed at 15.

A piston 16 has threaded engagement with the feed screw 8. Secured tothe piston 16 by screws 17 is a washer 18. The piston 16 and Washer 18are each provided with a cord or flat edge 19.

A shaving paste refiller tube 20 made of glass, celluloid or othertransparent material is provided for use with the feed mechanisms.threaded at each end and is formed with a straight guide wall 21adjacent the straight edges of the piston 16 and washer 18 to hold thepiston against rotation and thereby permit longitudinal feeding of thesame when the feed screw 8 is rotated by turning the knurled button 13.i

The tube 20 contains paste in the form of a cylinder extendin to thethreaded portions of said tube. 6ne end of the tube 20 is threaded ontothe threaded portion 2 of the head 1. The screw .8 is then insertedthrough the paste in the tube with the piston 16 seated against theouter end of the cylinder of paste. The retaining cap 12 is thenthreaded into the second end of the tube 20, thereby holding the tube inplace to The refiller tube 20 is internally Ill til

form a part of the handle of the shaving brush.

Normally the plunger rod 7' rejects through the outlet passage t to cose the same against the escape of the paste when the shaving brush isnot in use. To 0 en the passage 4, the knurled button 13 is rst rotatedin one direction until the shoulder 10 of the screw 8 contacts the innersurface of the end wall of the cap 12 as indicated in dotted lines inFigure 1, which withdraws the plunger 7 and opens passage 4. By nowrotating button 13 in the reverse direction, and at the same timeretaining the same against longitudinal movement, the piston 16, whichcannot rotate, due to its fiat edge 16, will be advanced in the tube,thereby forcing a quantity of the paste into the recess 3 and outthrough the passage 4 between the hairs or bristles 6 of the brush. Whenit is desired to check the feed of aste further free rotation of button13 wi 1 cause it to move to the left, its resistance to such movementbeing less than that of piston 16, thus causing stem 7 to re-enter andclose passage 4, and at the same time forcing the contents of saidpassage 4 into the brush bristles. It will thus be seen that apredetermined quantity of paste may be fed to the brush hairs with eachadvance of the plunger plate 16.

When the paste in the tube has been used up the tube 20 is removed and afull tube inserted in its place. i

I am aware that numerous details of construction' may be varied througha wide range without departing from the principles of this invention,and I therefore do not purpose limiting the patent granted other wisethan necessitated by the prior art.

I claim as my invention:

An ejector for brushes and the like, comprising a head, amaterial-carrying tube secured to said head and forming a handletherefor, a rotatable screw rod within said tube, a piston on said rodadapted to be shifted longitudinally in said tube by the rotationof'said rod, and a valve forming a continuation of said screw rod andadapted to open and close a discharge passage in said head, a rotationof said screw rod in one direction initially unseating said valve andthen moving said piston forward to feed the material through saiddischarge passage, its reverse rotation closing said valve.

In testimony whereof I have hereunto subscribed my name in the presenceof two subscribing witnesses.

GEORGE E. STOCKSETH.
